This Rostock mini G2s is a companion piece of our new upgraded delta 3D printer -Rostock mini G2. G2s is designed to support dual extruder. With G2s you can print a single two-color object, or you can print two objects in one print job, each made from a different color. You can also print one single-color object, as with other single-extruder 3D printers. Or you can use one extruder for infill or support. The 2 extruder motor pushes filament through 2 head separately, so mixing colors printing is not applicable for the moment. This G2s is powered by our newly designed control system—GT2560 that supports 2 extruders and eliminates the complicated wiring of Mega2560+Ramps 1.4 and it is more space-saving. An auto-leveling auto-calibration device is also added on G2; which means you do not have to adjust it every time before you start printing, after the first assembly work, you can almost plug and play. In terms of printing filament, G2s not only support PLA and ABS, Nylon and wood filament is also available, which enables more possibilities to create 3D printing project. This G2s is also improved with LCD control panel; you can monitor the printing process in real time and with a SD card it can realize stand-alone printing, very convenient.

Assembly Tips
These assembly tips are community provided, and 'are not official Geeetech recommendations.
Use at your own risk. If in doubt, contact Geeetech directly for supported assembly assistance.
Z-Probe Switch and Rod-End Bearing Installation Order
The G2/G2S Build Manual (as of Sept 4, 2015) has the Z-Probe Switch installation procedure before the Rod-End Bearings procedure.
If done in that order, the Z-Probe Switch will prevent the installation and tightening of the Rod-End Bearing retaining bolts.
Reorder the building instructions as follows:
- Proceed through the manual until you reach the Z-Probe and Switch installation section.
- Skip ahead, and install the Spider's Rod-End Bearings (but not the Diagonal Rods themselves)
- Return to the Z-Probe and Switch installation chapter.
- Continue instructions as per normal from the point after the Z-Probe Switch installation
Z-Probe Switch Installation
For the Z-Probe switch, you are required to screw through both the switch and the spider with the M3 retaining bolt.
Before installing on the spider, screw both bolts through the switch until the ends are flush with the opposite side of the switch.
When installing on the spider, tighten each bolt a 1/4 turn at a time, until both bolts have begun to screw into the spider, then tighten normally.
There should be no more than a 1mm gap between the Z-Probe Switch and the spider.
Smooth Rod Tightening
It can be difficult to tighten the lubricated smooth rods by hand. If you have a pair of vice-grips, you can pad the jaws (foam or cloth to prevent scratches to the smooth rods) and clamp down tightly.
Building Modifications
The following are community provided modifications to the Geeetech Delta Rostock G2/G2S, and are not provided by nor approved by Geeetech. Use at your own risk.
Z-Probe Lock Ring
If you have problems with the Z-Probe lock ring slipping, or are worried that your will strip the plastic threads in the lock ring while tightening the jam bolt, simply file a flat into the Z-Probe at the location where the lock ring will be.
Then, the lock ring will be unable to slip.
G2S J-Head Orientation
The G2S build documentation leaves the orientation of the J-Head up to the user. Many different orientations are possible.
Frame Tightness Solution
If your frame is wobbly, the problem may be that the acrylic base plates are slightly thinner than specified.
To check, use a caliper to measure the thickness of the top and bottom acrylic base plates.
If they are in spec (8mm or slightly thicker) then do not perform this modification - your frame issues are elsewhere.
If your base or top acrylic plates are thinner (for example, in my G2S the base plate was 8mm, but the top plate was 7mm), you will be able to feel the end of the smooth rod slightly protruding through the acrylic, instead of inset, as required to stiffen the frame.
To resolve this issue, remove the suspect acrylic plate, and replace the single M8x1mm washers on the smooth rod ends with either two M8x1mm washers, or a single US 5/16th" x 1/16th" (approx 8mm x 1.5mm) washer. Note that all of the washers for the plate must be identical.
